使用MySQL IN()显示多个选定的行

2024-04-26 07:00:04 413

让我们首先创建一个表-

mysql> create table DemoTable1045
(
   Id int NOT NULL AUTO_INCREMENT PRIMARY KEY,
   FirstName varchar(100)
)AUTO_INCREMENT=100;

使用插入命令在表中插入一些记录-

mysql> insert into DemoTable1045(FirstName) values('John');
mysql> insert into DemoTable1045(FirstName) values('Chris');
mysql> insert into DemoTable1045(FirstName) values('Robert');
mysql> insert into DemoTable1045(FirstName) values('Mike');
mysql> insert into DemoTable1045(FirstName) values('Adam');

使用select语句显示表中的所有记录-

mysql> select *from DemoTable1045;

这将产生以下输出-

+-----+-----------+
| Id  | FirstName |
+-----+-----------+
| 100 | John      |
| 101 | Chris     |
| 102 | Robert    |
| 103 | Mike      |
| 104 | Adam      |
+-----+-----------+
5 rows in set (0.00 sec)

以下是MySQL查询以显示多个选定的行-

mysql> select *from DemoTable1045 tbl where(tbl.Id, tbl.FirstName) IN ((101, 'Chris'), (102, 'Robert'), (104,'Adam'));

这将产生以下输出-

+-----+-----------+
| Id  | FirstName |
+-----+-----------+
| 101 | Chris     |
| 102 | Robert    |
| 104 | Adam      |
+-----+-----------+
3 rows in set (0.05 sec)
